I really like how she looks, seems like she's a mysterious girl hã? And the shadow looks great too, I don't know what to expect from it though, I can't predict it by it's expression... but that' s good thing! ;D Are you going to write a comic book or something?
Aw ! I wish we could know more about this character I recognized her thanks to your picture Shadows I just love how you did the colouring... and how you do textures ! even without backgrounds, your pictures never look "empty", they are always very harmonious. I admire you !
